The story – accompanied by a new photograph – said the newspaper mistakenly used an archive photograph of Frank Calabrese, who founded a small printing company, accepting an “Excellence in Manufacturing” award in 1988.

“The newspaper erroneously used that photograph in its graphic describing Tuesday’s mob indictment,” the article said.

Tribune spokeswoman Patty Wetli said it was “unfortunate that Mr. Calabrese has chosen to take this step after we expressed our regret and did all we could to correct the error.”

Meanwhile, the Tribune also is investigating the accuracy of a photograph that ran in Wednesday’s editions, Wetli said.

That photograph, which the newspaper said in another story was taken by a college student, identified a man as Joseph “The Clown” Lombardo, a 76-year-old reputed mob boss who is on the lam after being indicted Monday along with Frank Calabrese Sr.

But a man identified as Stanley Swieton told Chicago reporters he was the person in the picture. A telephone listing for Swieton could not be found.
